Can someone direct me to reference table which list the recommended torque values for small, stainless steel installation or mounting hardware when mounting 6061 Aluminum Electronic part(s) into Military Electronic Systems. Application environments can range from Ground Fixed, Ground Mobile, Naval and Airborne, etc.
The size of mounting hardware; we typically use with our products is in the 6-32, 8-32 and 10-32 UNC-2B size range.
Mil-Hdbk-60 dated 12 March 1990 which replaced Appendix A12 of Fed-Std -H28; stipulates torque values from 0.190 upto 1.5 inch diameter fastners or hardware.
However, I'm still in need of some recommended torque values for the smaller hardware fasteners. These range from size(s) of 0-80, 2-56,4-40, 6-32 and 8-32 UNC-2B, and 10-32.
Applications are sometimes into Heli-coil inserts and other time directly into the raw 6061 aluminum tapped holes.
Any Ideas?
Please can anyone help?
Humbly,
Mr. Ed
